PROTECTION PRODUCTS - EMIClampTM
Description
The EClampTM2410P is a combination EMI lter and line
termination device with integrated TVS diodes for use on
Multimedia Card interfaces. This state-of-the-art de-
vice utilizes solid-state silicon-avalanche technology for
superior clamping performance and DC electrical char-
acteristics. They have been optimized for protection of
T-Flash/MicroSD interfaces in cellular phones and other
portable electronics.
The device consists of six circuits that include series im-
pedance matching resistors and pull up resistors as re-
quired by the SD specication. TVS diodes are included
on each line for ESD protection. An additional TVS diode
connection is included for protection of the voltage (Vdd)
bus. Termination resistor value of 45 Ohms is included
on the DAT0, DAT1, DAT2, DAT3, CMD, and CLK lines.
Pull up resistors of 15k Ohms are included on DAT0,
DAT1, DAT2, and CMD lines while a 50k Ohm pull up is
inlcuded on the DAT3 line. These may be congured for
devices operating in SD or SPI mode . The TVS diodes
provide effective suppression of ESD voltages in excess
of ±15kV (air discharge) and ±8kV (contact discharge)
per IEC 61000-4-2, level 4.
The EClamp2410P is in a 16-pin, RoHS/WEEE compliant,
SLP4016P16 package. It measures 4.0 x 1.6 x 0.58mm.
The leads are spaced at a pitch of 0.5mm and are n-
ished with lead-free NiPd.
